Commercial sealant in Bermondsey

Guest bathrooms are cleaned every day and used by different people every night, so sealant there has a hard life. Rooms are resealed in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. If you are dealing with repeated reseals that don’t last and split sealant where wet room floors meet walls, we can put it right.

In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Bermondsey, and room-by-room programmes can be planned where needed.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

How it works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes as long as the scope needs, from one welfare room to a full building, including the tidy-up. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Bermondsey. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. Tell us the rooms, hours and site rules, and we’ll plan the programme.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. In each room, the old bead comes out and the joint is cleaned and treated.
  4. We reseal with the right product for each joint.
  5. Each finished area is checked with you and given a cure time.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Move anything stored near the joints
  • Tell us about any previous sealing or DIY attempts

Aftercare tips

To keep the joints looking good and working properly:

  • Check extract fans are actually running
  • Do not leave a failed joint until the next refurbishment
  • Pass on the cure time to whoever cleans the rooms
  • Note the date each area was done

Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints.

Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, before they become leaks that take the room out of use.

Your questions about commercial sealant in Bermondsey

Is parking an issue for commercial sealant in Bermondsey?

Parking in Bermondsey, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Do you work for hotels and guest houses in Bermondsey?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Is there any odour?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do you remove the old sealant?

Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

Can you seal over the old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.

When can guests or staff use the shower again?

Usually after around 24 hours. We give a cure time for each area.

Do you work for landlords and letting agents?

Yes. For several properties, we can plan the work as one programme, fitting around access to each property.

Honest limits

In fairness, there are a few things sealant won’t fix:

  • Faulty shower valves and leaking traps
  • Assessing what fire stopping a building needs
  • Damaged sanitaryware that needs replacing

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

What we seal

  • Office washrooms & kitchens

Commercial buildings in Bermondsey

London has hard water, so limescale builds up on sealant, grout and fittings. Bermondsey has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

Schools such as Boutcher Church of England Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. For buildings such as St Mary Magdalen Bermondsey, any kitchen and washrooms need the same sealant care as any other building. Rented homes near London Bridge station change hands often, and we can quote for one property or a whole portfolio of rentals.

What affects the quote in Bermondsey

We don’t publish a price list, because jobs vary so much. The quote depends on:

  • How much old sealant there is and how hard it is to remove
  • Working hours on commercial sites
  • Which sealant suits the joint
  • How many areas need sealing

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Asking for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • A few pictures by email, if you can
  • The problem you’ve noticed
  • How we’d reach the joints
  • Whether it’s a home or a business

There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.

Can I do it myself?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Why deal with it now?

Guests and staff judge a building by its bathrooms. Mouldy silicone looks unhygienic, however hard housekeeping work, and cleaning rarely puts it right. New sealant does. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Bermondsey, the repair is bigger than the sealant job would have been.

Combining jobs into one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
